Low-dissipating push-pull SQUID amplifier for TES detector readout
arXiv:1810.04706
Abstract
We suggest SQUID amplifier configuration intended for millikelvin refrigerators where cooling power is limited and hence high power efficiency is desirable. The configuration operates the SQUIDs in class-AB rather than the traditional class-A. A proof-of principle demonstration at T = 4.2 K is presented.
